A Randomized, Open-label, Multicenter, Parallel-controlled Phase III Clinical Trial to Evaluate the Efficacy and Safety of TQB2102 for Injection Versus TCbHP in Neoadjuvant Treatment of Breast Cancer With Positive HER2 Expression
Sponsor
Chia Tai Tianqing Pharmaceutical Group Nanjing Shunxin Pharmaceutical Co., Ltd.
Enrollment
544 participants
Start Date
Sep 15, 2025
Study Type
INTERVENTIONAL
Conditions
Summary
This is a randomized, open, positive drug control, multi center phase III study. Through the evaluation of tpCR, bpCR, ORR, EFS, IDFS, OS , AEs and other indicators, it proves the effectiveness and safety of TQB2102 for injection versus TCbHP in the neoadjuvant treatment of HER2 positive breast cancer patients.
